Pomatiopsidae
Pomatiopsidae is a family of small, mainly freshwater snails, (some also occur in other habitats) that have gills and an operculum, aquatic gastropod mollusks in the superfamily Truncatelloidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). Pomatiopsidae are well known as intermediate hosts of Asian schistosomes. Distribution Species in the family Pomatiopsidae occur worldwide. The generic diversity of Pomatiopsinae is particularly high in the Japanese Archipelago, where four of the eight genera, including two endemics, are recorded. The subfamily Triculinae radiated as aquatic snails in freshwater habitats in Southeast Asia. Description The American malacologist William Stimpson first defined this taxon as Pomatiopsinae in 1865.

Pomatiopsis
''Pomatiopsis'' is a genus of amphibious snails with gills and an operculum, aquatic freshwater gastropod mollusks in the family Pomatiopsidae. ''Pomatiopsis'' is the type genus of the family Pomatiopsidae. Distribution The distribution of the genus ''Pomatiopsis'' includes the USA: West Coast of the United States, Midwestern United States and Eastern United States.Davis G. M. (1979). "The origin and evolution of the gastropod family Pomatiopsidae, with emphasis on the Mekong river Triculinae". ''Academy of natural Sciences of Philadelphia'', Monograph 20: 1-120. at Google Books Description In 1862, the American malacologist George Washington Tryon first defined this genus. Tryon's diagnosis reads as follows: Species There are four species within the genus ''Pomatiopsis'': * ''Pomatiopsis binneyi'' Tryon, 1863 * ''Pomatiopsis californica'' Pilsbry, 1899 * ''Pomatiopsis chacei'' Pilsbry, 1937 * ''Pomatiopsis cincinnatiensis'' (Lea, 1840) * ''Pomatiopsis hinkleyi'' Pilsbry, 1 ...

Oncomelania Hupensis
''Oncomelania hupensis'' is a species of very small tropical freshwater snail, an aquatic gastropod mollusk in the family Pomatiopsidae. Distribution ''Oncomelania hupensis'' has been found in China, Taiwan, and also in Japan, the Philippines, and on the Indonesian island of Sulawesi. Description Over the past a few decades, the taxonomy of ''Oncomelania hupensis'' has been a dispute due to the variation in morphological characters such as shell sculpture, operculum etc. Phenotypically, ''Oncomelania hupensis'' can be separated into ribbed- and smooth- shelled morphotypes. In China, the typical morphotype of ''Oncomelania hupensis'' is ribbed-shelled, and its distribution is restricted to Yangtze River basin. Smooth-shelled snails are also distributed in mainland China, but are considered the same species and subspecies of ''Oncomelania hupensis''. ''Oncomelania hupensis'' reported in other Far East countries are smooth-shelled, and have been considered either as su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freshwater Snail
Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. ''Ampullariidae''). Most feed on algae, but many are detritivores and some are filter feeders. According to a 2008 review of the taxonomy, there are about 4,000 species of freshwater gastropods (3,795–3,972). At least 33–38 independent lineages of gastropods have successfully colonized freshwater environments. It is not possible to quantify the exact number of these lineages yet, because they have yet to be clarified within the Cerit ...

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal ''Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Schistosome
''Schistosoma'' is a genus of trematodes, commonly known as blood flukes. They are Parasitism, parasitic flatworms responsible for a highly significant group of infections in humans termed ''schistosomiasis'', which is considered by the World Health Organization as the second-most socioeconomically devastating parasitic disease (after malaria), with hundreds of millions infected worldwide. Adult flatworms parasitize blood capillaries of either the mesenteries or plexus of the bladder, depending on the infecting species. They are unique among trematodes and any other flatworms in that they are Dioecy, dioecious with distinct sexual dimorphism between male and female. Thousands of eggs are released and reach either the bladder or the intestine (according to the infecting species), and these are then excreted in urine or feces to fresh water. Larvae must then pass through an intermediate snail Host (biology), host, before the next larval stage of the parasite emerges that can infec ...

Gills
A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (pl. branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including mollusks, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill chambe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
